Hello
Is it not possible to use AQB, specifically the steel design of cross sections modules, with loadcases from MAXIMA?
Right now my workflow is setting up combinations with MAXIMA, then using the TRAC command to find the loads that are governing for relevant maximum loads, and then running a new ASE with these combinations, so i can finally analyze them in AQB.
Problem is the specific element with maximum loads might change a bit for every meshing.
So is there an easier way?
Hello Morten,
Sure, why not. Bellow will be attached a sample of my code
+prog aqb
head x
echo full no
$---------------------------------------------------------------------------------------------
#include beam-aqb
lc 1 $loadcase you want to design for form your maxima
comb extr sum lc1 1 f1 1.0 lcst 9001 titl ‘xxxx’ $save results form loadcase 1 to 9001
stre e91 $save min/max results at case 91.
$---------------------------------------------------------------------------------------------
end
That worked, thanks.
Is there any reason why you cannot select MAXIMA envelopes in the window, but you can call them via teddy?
See below AQB window, only my defined loadcases (via combine loads module) show up.
AQB needs to know which (partial) cross-section to apply the respective internal forces (and sometimes also internal stress components) to. A MAXIMA overall envelope can only be related to one cross-section state, which is (imho) why MAXIMA-LC is not offered in SSD for AQB, as this could quickly lead to nonsense in AQB.

Thank you for your response.
So it means that MAXIMA makes sense to an extent, as long as construction stages are not part of your analysis?
Hello, But what do you do in case of composite section. I have a precast girder bridge. at stage 1 its a small precast girder. later on with CSM its after poring the deck it become composite. the method you suggest takes into account full section for the first stage.
– IdoBricknerIn case of composite section superpostion has to be done in aqb Only loads actiing On finał section can be superposed in maxima and the adres as envelope loadcase to aqb combination (live loads f.e.)
– micoDo you have maybe a sample code for that? if my final construction stage is 5050. I have a static loads present live loads. How can I superposition it in aqb? lets say I would like combination that takes the last stage, add to it thermal loads both directions and than a the list od live loads, each time it takes one load into account and shows the envelope of it.
